How it works
Three steps, and the third one repeats.
Choose something you want to read
The hundred most-read public-domain books in your language are one tap away, and the whole catalogue is searchable. Or paste an article, a note, song lyrics, or the address of a page.
Read, and tap what you don't know
A tapped word shows its meanings in your language, with the sentence it came from. Ask for a translation of the sentence when you want one, or a grammar note. Have the text read aloud at normal or slow pace.
Let the words come back to you
Every word you meet has a level: New, Recognise, Understand, Use. Reading and short reviews are the evidence; the model suggests a change and you decide. Nothing moves without you seeing why.
Features
Everything a reader needs, nothing a game needs.
A library that starts full
Real books, in the original language, with a cover, a level estimate, and the share of words you already know shown before you open them.
A reader built for not knowing yet
Meanings in context, sentence translation on demand, grammar notes, a sentence-structure view, and your own notes on any word.
Dictionaries you choose
Wiktionary, DeepL and AI meanings, enabled and ordered per language pair. Every saved meaning remembers where it came from.
A model that shows its work
Your self-assessment is the starting point. Each word keeps a complete audit trail, and the Help page documents every weight and rate.
Reviews that fit the day
Due words return in short active-recall sessions graded Again, Hard, Good, or Easy. No leaderboards, no guilt, no streak to protect.
Progress you can trust
Reading, vocabulary and activity per language, with an estimated CEFR level worked out from the words you actually know.
